DAVID FROEHLICH, OF NEW YORK, N. Y.

p LOCK FOR VEHICLES.

To all iiihom it may concern:

B'e it known that I, DAVID FROEi-ILICH, a

subject of the Emperor of Austria-Huncounty 'of New York and State of New York,;haye. invented certain new and useful' ;lm provements in Locks for Vehicles, of

,jwhich thefollowing is a specification, such as will. enable those skilled in the art to w-hiel it app'ertai'ns to makeand use the s 1e-..- v 1 a y This invention relates to locks for. ve-

.hicles, and'the object thereof is to provide an mproved device'of this class designed particularly for use in connection with what are knownas push carts or delivery carts, but which may be used in vconnection with various kinds and classes of vehicles. and with this and other objects in View the invention consists in a device of the class specified constructed as hereinafter described and claimed.

The invention is fully disclosed in the fol- I lowing specification of which the accompanying drawing forms apart, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which 'l- Figure 1 is a side view of an ordinary push ordelivery cart'provid edwith my im proved lock.

Specification of Letters Patent. I Patented Feb. 22 1910. Application filed October 20, 1909. Serial No. 523,643. I

with the usual side wheels a and at the front of the vehicle is a center or guide wheel 0: connected with the bed or body by a suitable support a which is secured to saidbed or bodyi butit will be understood that the vehicle proper may be of any desiredconstruction and may have a running gear or truck construction of any kind or class. In the construction shown my improved lock 7) is secured to and transversely of the bottom a of the bed or body a and is provided with a lock bolt 6 adapted to be projected between twoofthe spokes of one of the wheels so as to lock the vehicle. v Thelock 7) comprises an oblong casing Z2 having a removable cover 6* and the bolt 6- of the lock is movable through oneend portion 6 of the casing bf. which for the purpose of this description will be called the righthand end of said casing, and said bolt \2 is preferably provided with a head I). The cover 22 of the casing b of the lock may be connected with said casing by corner screws. bolts or pins b, or in. any desired manner, and said casing is provided centrally thereof, in theconstruction shown; with two studs or pins which are con nected with the bottom of said casing in any desired manner and between which the bolt Z2 is movable. and secured to the inner end of said bolt is a contractilespring c which is also secured to the end of said casing oppositethat through which the bolt 6 passes, as shown at 0 hand portion of the casing b and adjacent I to said end is a transverse bearing or support Tithin the right (l may be turned. An arm e is pivoted centrally of the casing b as shown at e and a spring 7 is secured at f and bears on the arm 6 and said, spring is'held in an operative position by a pm or stud. f. In the construction shown the inner end portion of the bolt 6 is rectangular in cross section and is provided with a longitudinal recess f in which the arm e operates and said bolt is also provided with stops or shoulders f which limit the outward movement thereof. The arm 6 is also provided at its free end with a transverse nose piece or projection 6 adapted to enter a recess ein the adjacent side of the bolt 6 and a lever g is pivoted between the arm.e and the end 6 of'the casing 6 as shown at 9 by means of a pin cast in or secured in said lever, and one end of Y said lever is pivoted to the arm 6 at and 20 of construction shown, by the bolts or similar devices I), and the normal position of the parts of the lock is that shown in Fig. 2 in which the bolt 6 is withdrawn into the easin b by means of the spring 0. lVhenever it is desired to lock the vehicle, the bolt is pulled out by grasping the head 72 until it projects between the spokes of the adjacentwheel a, as shown in F ig. l, and at the limitof this outward movement the arm (-2 is forced inwardly by the spring 7' and the transverse nose or; projection e at the .free end of said arm enters the recess 6* in said bolt, as shown in Fig. 3, and the vehicle is locked. lVhenever it is desired to unlock the vehicle the key (Z is inserted through the. opening or aperture d and engages the end (Z of the spindle (Z and said key is turned to the left. This operation forces the outer end of the lever g inwardly and the inner end of said lever outwardly and the free end of the arm 6 is also thrown outwardly and disengaged from the bolt Z1 and the spring 0 withdraws said bolt into the position shown in Fig. 2 and the vehicle is unlocked.

In Fig. 6 I have shown a modification by means of which-the bolt may be locked in both 1ts innermost and outermost positions and all that is necessary to accomplish this result is to provide said bolt with a supple mental recess 2' adapted to receive the nose iece or projection e of the arm a when said olt. is in its innermost position. \Vith this form of constructionthe lever 9 must be operated by means of the key J and the the operator thereof, and this is sometimes done when said carts or vehicles are loaded with articles to be delivered but with my improvement the stealing of such carts or vehicles is made impossible.

Although I have shown and described my improved lock as applied to a push cart or similar vehicle it will be apparent that the use thereof is not limited to vehicles of this class and the saidlock may be employed in connection with other kinds or classes of vehicles or wherever such a device may be used. M y invention is also not limited to the exact details of the construction herein shown and described and various changes therein and modifications thereof may be made within the scope of the appended claims without departing from the spirit of my invention or sacrificing its advantages.

'Having fully described my invention wha I claim as new, and desire to secure by Letters Patent is 1. A look device of the class described, comprising an oblong casing. a bolt movable through one end thereof, a spring for drawing said bolt intosaid casing. a spring OPtl ated arm pivoted centrally of said casing and extending in the direction of the end thereof through which said bolt is movable. said arm being adapted to engage said bolt when in its outermost position, a lever pivoted between the free end of said arm and the end of the casing through which said bolt is movable. the inner end of said lever being pivotally connected with said arm-am gear teeth and a key operated spindle mounted in the end portion of said casing throughwhich said bolt is movable and provided with a pinion which meshes with suit gear teeth.

2. A lock of theclass described, comprising a casing, a bolt movable through one end thereof, a spring for drawing said bolt into said casing. a spring operated arm pivoted centrally ofsaid casing and extending in the direction of the end thereof through which said bolt is movable, said arm being adapted to engage said bolt both in its innermost and' outermost position, a lever pivoted between the free end of said arm and the end of the casing through which the bolt is movable, the inner end of said lever being pivoted to said arm and the out r end thereof being provided with gear teeth, and as my invention I have signed my name in a key operated spindle mounted in the end presence of the subscribing witnesses this portion of said casing through which said 18th day of October 1909.

bolt is movable and provided With a pinion DAVID FROEHLIGH. 5 adapted to engage with the teeth of said Witnesses:
